SDK 2.0 leads to fatal exceptions

[Stational]

i Upgraded to SDK 2.0, i added the New required function to my user_init file. The code still compiles and uploads fine but after Boot the esp8266 just prints fatal exceptions to the console. With SDK 1.5.4 everything works fine.

Please note the fatal exception vector address and find it in the assembly file of the code that you burned into the ESP8266. You will be able to locate the exact issue that triggers the exception!
